## chasepdf2csv
#!/usr/bin/env ruby
# chasepdf2csv -- Convert Chase credit card statements from PDF to CSV. Written
# to easily import older statements into QuickBooks Online/Self-Employed. Chase
# unfortunately only offers statements up to 6 months in the past, making it a
# huge chore to synchronize past transactions.
#
# How to Use
# ----------
# This script requires Ruby >2.0.0 and pdftotext. Copy this script somewhere and
# make it executable. Run it like any other command.
